Title: Improvements in mercerisation
IPC: D06M13/438
Filed: 1935-11-04
Abstract: Derivatives of sulphamides of the benzene series containing a side chain having at least three carbon atoms and, attached to the nitrogen atom a residue containing a hydroxy group are used in mercerising processes as wetting agents.  Optional additions comprise (a) agents which prevent foaming, e.g. aliphatic hydrocarbons or alcohols of high molecular weight, (b) organic solvents, e.g. aliphatic, aliphaticaromatic or hydroaromatic alcohols such as butyl, amyl or hexyl alcohol, methylcyclohexanol, benzyl alcohol, terpene alcohols, glycerine and ethers, e.g. glycolmonobutylether, diethyleneglycolmonobutylether, (c) substances employed in mercerizing lyes for promoting solution, e.g. phenols, cresols, xylenols, halogenphenols, alkali stable sulphonation products of fatty compounds, Twitchell's reagents, mono and polyhydric alcohols and ketones.  In examples: (1) to a caustic soda mercerizing bath is added a sulphonamide obtained from crude cymene (sulphite turpentine oil) by sulphonating with chlorsulphonic acid and condensing the resulting sulphochloride with monoethanolamine after extraction with benzene; (2) the same sulphamide as is employed in example 1 is used in association with a Twitchell product derived from phenol and oleic acid or with a mixture of pine oil, caustic potash and a sulphonated mixture of castor oil and sulphophthalic anhydride.  Sulphamide derivatives of cumene, cymene, butylbenzene and chlorcymene containing a residue with at least one hydroxy group attached to the nitrogen are mentioned.  Methylol compounds of sulphamides and sulphamides derived from amines of the sugar series containing more than one hydroxy group, e.g. glucamine may also be employed.  As residues containing hydroxy groups, oxyaryl residues, oxyacyl residues, e.g. the glycollic acid residue and ethers of polyhydric alcohols having at least one free hydroxy group are specified.  The Specification as open to inspection under Sect. 91 comprises also the use in mercerizing of any sulphamide of the benzene series having a side chain containing at least three carbon atoms. In an additional example, a sulphamide obtained from crude cymene sulphochloride and ammonia is employed.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to addressing or like printing machines
IPC: B41L47/58
Filed: 1926-12-03
Abstract: 262,459. Adrema Maschinenbauges. Dec. 4, 1925, [Convention data]. Addressing-machines; stopping and starting arrangements.-An addressing or like printing machine is driven from a motor 12, Fig. 1, through a clutch 15, which is disengaged to stop the machine bv hand or after a certain number of addresses have been printed. Bowden cables 34, 36, 35, 36<1> extend to a common disengaging pawl 30 from a hand-control 40<1> and from positions on (a) the guide track 11 of a bar 10 attached to a testing-strip 9, (b) the addressplate guide track 7, and (c) a hopper 8 into which the address-plates are delivered after printing. The clutch comprises a rotary disc 14, Fig. 3, carrying a spring-pressed plunger 16 adapted to engage a hole in a disc 18 from which the operative parts are actuated. To start ths machine, a pedal 24 is depressed, and a bevelled plate 19 on the end of a rod 20 fixed to the pedal is thereby lowered out of engagement with the plunger 16, which is thus released and drives the disc 18. A pawl 25 also connected to the pedal is simultaneously moved behind a projection 29 on the pawl 30 and is held in that position until the pawl 30 is raised by a pull exerted on one of the cables. The pawl 25 is then released and returns to normal position, and the rod 20 returns under spring pressure and withdraws the plunger 16. (a) When the required number of addresses has been printed on the strip 9, the bar 10 strikes against a catch 51, Fig. 10, and so releases a spring-pressed lever 53 attached to the cable 36. In a modification, the bar 10 acts through a pawl fixed on the pivot 50 of the catch 51, so that if the pedal 24 is inadvertently depressed after the bar has reached its locking position, the bar may still move forward, and no damage is caused. (b) The cable 35 is connected to one arm 45, Fig. 11, of a bell-crank, which is moved round when the end 44<1> of the other arm 44 comes opposite a recess 6<11> in a special stop plate 6'. (c) When the hopper 8 is full, its base plate 63, Fig. 1, strikes against a dog 62 on the end of the cable 36' and stop the machine.

Abstract: 959,810. Making punches and dies. WILLIAM CROSLAND Ltd. Aug. 27, 1962 [Aug. 25, 1961], No. 30693/61. Heading B3A. [Also in Division B4] A method of making a blanking die of the type comprising male and female die parts formed from hard plywood and having shear edges formed by hardened steel members comprises sawing the punch and die plate baseboards to produce through apertures therein corresponding to the article to be blanked, locating steel rule inserts within the apertures and retaining them therein by the use of cores formed during the sawing operation, blanking at least one steel plate with the die so produced, removing the insert and the core from the die plate baseboard and securing a blanked steel plate on the die baseboard so that its sheared edge overlies the aperture in the die plate baseboard, thereby to produce a die of the kind in which blanked shapes can be ejected through the apertures in the die plate baseboard. Two baseboards having the same or different thicknesses 10, 11 are located together by dowels and a D shape is cut therein using a saw having twice the thickness of the hardened steel rules 15 which form the shearing edges of the die, to produce cores 16. The rules 15 have a depth equal to the surround of the baseboard 11. The die baseboard 11 is assembled by locating an insert 15 in the cut-out, inserting therein a packing 17 having a thickness equal to that of the rule 15 and forcing the core 16 cut from the punch baseboard 10 into the space formed by the rule to wedge the rule into position. The punch baseboard 10 is assembled by lining the cut-out with packing (not shown), locating the insert 15 adjacent the packing and forcing the core 16 cut from the baseboard 11 into the space formed by the rule to wedge the rule into position. Ejection members 18, preferably of rubber, bushes 20 and guide pins 19 are secured to the baseboards 10, 11 respectively. One or more steel plates 21 preferably of stainless steel or annealed tool steel are blanked and pierced by the die. After removing the rule 15, packing 17 and core 16 from the die baseboard 11, one of the blanked plates is located and attached to the die 11 so that the edges of its blanked aperture overlap the aperture of the die 11 by an amount equal to the thickness of the originally located insert 15. The die may be used for shearing and trimming sheet metal and plastic shapes.

Filed: 1950-05-05
Abstract: 701,571. Cartridge clip filling mechanism. FRENCH & SONS, Ltd., T. Aug. 3, 1951 [May 5. 1950], No. 31130/49. Class 92(2) Mechanism for charging cartridges into clips comprises means for loading the cartridges into the recesses 14 of a carrier 12, means for presenting a clip to the ends of the cartridges in the carrier, and means for moving the clip and loaded carrier relatively to each other to force the cartridges into the clip. In the construction shown, the carrier forms part of a carriage 5 which, by means of a pin 10 and a cam 9, reciprocates beneath shoots 3 and 15 supplying the cartridges and clips respectively. As the carriage moves to the right, and towards the end of its movement, a lug 34 thereon engages a tang 33 on a plate 31 thus moving the plate clear of the shoot 3 and allowing cartridges to enter the three recesses to the left of the carrier 12. The remaining two recesses are filled during the return stroke. A cam in the shoot and chamfered edges in the recesses 14 combine to locate the cartridges so that they are correctly presented to a clip at the base of the shoot 15. A clamp 17 bears on the cartridges as they are moved by carriage 5 into the clip and a block 18 bears against the end of the clip during the filling operation. A cam 20 releases the block when the clip is filled, and the filled clip continues to move to the left, and when it is adjacent a discharge shoot 23 a cam-actuated member gives it a quick upward movement which sends it clear of the carrier and thence down the shoot. In the meantime a lug 35 on the carriage has returned the plate 31 to the original position. Devices are provided in the shoots 3, 15, for releasing the cartridges and clips in the required manner.
